Miniature DC/DCs tout lowest cost for regulated 2-watt apps

Stoughton, Mass.—MicroPower Direct's D200ERW series of miniature single- and dual-output DC/DC converters, part of the company's "Budget Saver" family, features a tightly regulated 2-watt output in a single in-line package for data acquisition systems, telecom equipment, battery powered and battery backed instrumentation, industrial control systems, and board level power distribution subsystems.

The series, in thirty six models, provides 3.3, 5, 9, 12, 15, 24, &plusmn5, &plusmn12, and &plusmn15 VDC from a 9-to-18, 18-to-36 or 36-to-72 VDC input. Standard features include a line regulation of at least &plusmn0.5 percent, load regulation of &plusmn0.75 percent or better (single-output models; &plusmn1 percent for dual-output models), and maximum ripple and noise of 100 mV p-p (single-output models; 150 mV p-p for dual-output models). Operating efficiency is as high as 85 percent. Input/output isolation is 1,500 VDC. These DC/DCs include continuous short-circuit protection. MTBF (per MIL HDBK 217F) is greater than 1 million hours. All models are RoHS compliant.

The product datasheet will be posted shortly; click here. The D200ERW family, measuring 0.87-by-0.47-by-0.37 inches, is rated for operation over -40 to +85&degC with no derating or heat sinking required. Cooling is by free-air convection. The modules are priced at $7.20 and $8.65 each, depending on model, both in 100s. Delivery is stock to six weeks.
